Job Title: Data scientist Job Type:
Freelance (B2B contract) Location: Spain Work regime: Fully remote Keywords: ML, LLMs, AI, Python and AWS
Position Overview: We’re looking for a
data scientist
(minimum
2+ years of experience ) who is passionate about
Natural Language Processing (NLP), Generative AI, and
traditional machine learning —and who knows how to ship high-impact, production-grade models. This is a hands-on role where you’ll work across the full ML lifecycle: from prototyping to deployment, with a strong emphasis on
production-readiness, APIs, and scalable architecture. You’ll collaborate with AI engineers, product managers, and domain experts to develop intelligent systems that power next-generation insights for the pharma industry.
What you'll do: Design and develop NLP and generative AI solutions using LLM frameworks like
LangChain ,
LlamaIndex ,
CrewAI, or direct
model provider SDKs/APIs
(e.g., OpenAI, Anthropic, HuggingFace). Build and fine-tune traditional ML models (e.g., classification, regression, clustering) to support data-driven applications. Create robust and scalable
AI pipelines and APIs
using
Python
and
FastAPI. Deploy models to production using
AWS services
such as
ECS ,
Lambda, and
S3, with attention to CI/CD, observability, and cost-effectiveness. Apply strong
system design principles
to architect scalable, maintainable, and secure ML systems. Use
critical thinking
to analyze complex problems, identify edge cases, and propose pragmatic, data-driven solutions. Think creatively and
outside the box
to explore new ML techniques, tools, or approaches that push the boundaries of what we can do. Work closely with cross-functional teams to turn ambiguous business problems into well-scoped, technically sound AI solutions. Contribute to a culture of technical excellence and innovation in a fast-moving AI/ML team.
What you bring: Minimum 2 years of industry experience in data science or machine learning. Strong background in NLP, LLMs, and generative AI—comfortable with both the theory and tooling. Familiarity with modern LLM stacks such as LangChain, LlamaIndex, CrewAI, or similar. Skilled in traditional ML methods using libraries like scikit-learn, XGBoost, etc. Expert-level Python programmer (beyond notebooks)—you write clean, maintainable, testable code. Experience exposing models as production-ready APIs using FastAPI (or similar frameworks). Strong understanding of AWS services—especially ECS, Lambda, and S3. Experience with MLOps and DevOps best practices is a plus (e.g., Docker, Terraform, Azure DevOps, Github Actions). Proven ability in system architecture, problem-solving, and independently leading projects from concept to deployment. Comfortable working independently in a fast-paced, collaborative, remote-first environment. A little about us: Innova Solutions is a diverse and award-winning global technology services partner.
